Introduction to Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Hydroxypropyl Methylcellulose (HPMC), whose Chinese name is hydroxypropyl methylcellulose, is a semi-synthetic, non-ionic cellulose ether obtained by chemically modifying natural cellulose. This white powder can form a transparent viscous solution after dissolving in water. It has excellent thickening, water retention, stability and film-forming properties. It is an indispensable multifunctional additive in many fields such as construction.

Characteristics and advantages of Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Excellent water solubility: It can be quickly dissolved in cold water to form a clear and stable solution.

Efficient thickening and water retention ability: Increase the viscosity of the material, effectively reduce water evaporation, and improve work efficiency.

Good stability: It has good stability to acids, alkalis, and salts, and is suitable for a wide range of pH values.

Film-forming and protective effects: After drying, it forms a tough and transparent film to protect the substrate and prevent water penetration and evaporation.

Non-toxic and non-irritating: It has good biocompatibility and is suitable for the fields of medicine and food.

Adjustability: By changing the degree of substitution and molecular weight, its performance can be adjusted to meet different application requirements.

Hydroxypropyl Methyl Cellulose (HPMC)– Product Specifications

Fundamental Info

CAS Number: 9004-65-3
Chemical Call: Hydroxypropyl Methyl Cellulose
Molecular Formula: C₈H₁₆O₆ (duplicating system).
Look: White to off-white, free-flowing powder.

Secret Physical and Chemical Residences

HPMC is a non-ionic cellulose ether made from natural cellulose. It liquifies quickly in cold water but does not liquify in warm water over its gelation temperature. The item develops clear, colorless solutions with great film-forming capacity. It stays steady over a large pH array (commonly 3– 11).

Thickness varies by grade. Common thickness varieties consist of 5 mPa · s to 100,000 mPa · s at 2% focus and 20 ° C. This enables customers to select the right kind for their specific demands– whether for enlarging, binding, or water retention.

Purity and High Quality Criteria

The product satisfies major pharmacopeial requirements, consisting of USP-NF, EP, and JP, when used in pharmaceutical applications. For commercial use, it follows appropriate food and building sector standards.

Typical assay (dry basis): ≥ 99.5%.
Loss on drying out: ≤ 5.0%.
Residue on ignition: ≤ 1.5%.
Heavy steels (as Pb): ≤ 10 ppm.
Arsenic: ≤ 3 ppm.

Storage space and Handling

Shop HPMC in an amazing, completely dry location away from dampness. Maintain containers securely shut. The shelf life is normally 24 months when kept properly. Stay clear of direct exposure to guide sunshine or high moisture.

Common Applications

HPMC is commonly used in structure materials (like ceramic tile adhesives and provides), drugs (as a tablet binder or controlled-release agent), food (as a thickener or stabilizer), and cosmetics (for structure and dampness control). Its versatility comes from constant efficiency, security, and compatibility with many various other active ingredients.

Applications of Hydroxypropyl Methyl Cellulose (HPMC) CAS 9004-65-3

Building and construction Industry

Hydroxypropyl methyl cellulose (HPMC) plays an essential role in contemporary building and construction products. It is added to cement-based products like ceramic tile adhesives, plasters, and self-leveling compounds. HPMC boosts workability by maintaining water, which helps cement moisten appropriately. This results in more powerful bonds and less cracks. The compound additionally decreases drying time, providing workers even more time to use and smooth the material.

Drugs

In medication, HPMC serves as a secure and effective active ingredient. It is frequently used in tablet computers as a binder or finish representative. The material regulates just how quickly a medicine liquifies in the body, making certain stable release over time. Eye drops typically consist of HPMC also– it serves as a lubricant to eliminate dry skin and irritation. Due to the fact that it is safe and well-tolerated, governing agencies accept its use in many dental and topical medicines.

Food Market

HPMC is likewise accepted as a preservative (E number E464). It works as a thickener, stabilizer, and emulsifier. You can locate it in low-fat foods, baked products, and dairy options. It assists preserve texture and protects against separation of components. Considering that it is plant-based and gluten-free, it suits numerous dietary needs.

Other Makes use of

Past these major areas, HPMC appears in paints, cosmetics, and agricultural items. In water-based paints, it improves viscosity and prevents pigment settling. Skin care lotions utilize it for smooth application and moisture retention. Farmers apply HPMC in seed coatings to sustain germination and secure young plants. Its adaptability originates from being water-soluble, chemically stable, and suitable with lots of other materials.

5 FAQs of Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Frequently Asked Questions About Hydroxypropyl Methyl Cellulose (HPMC)

What is HPMC?

HPMC stands for Hydroxypropyl Methyl Cellulose. It is a white or off-white powder made from natural cellulose. People use it in many products like medicines, food, and building materials. It dissolves in cold water and forms a clear, thick solution.

Is HPMC safe to use?

Yes, HPMC is safe. Regulatory groups like the FDA and EFSA approve it for use in food and drugs. It passes through the body without being absorbed. That means it does not cause harm when used as directed.

What does HPMC do in construction products?

In construction, HPMC improves workability and water retention in cement-based materials. It helps tile adhesives, plasters, and renders stay smooth and easy to apply. It also stops them from drying too fast, which makes the final product stronger.
